[0002] Energy storage cabinet is a device that can store electrical energy, usually composed of battery packs, converters, control chips, etc. It can store electrical energy and release it for power supply when needed, usually used to provide backup power and stabilize grid voltage.

[0003] The AC electrical part of the energy storage cabinet needs to be assembled, debugged and repaired in the cabinet, which is very inconvenient. The pull-out structure can pull the electrical part out, greatly saving manpower and material resources during assembly, debugging and maintenance, and saving costs. The slide rail type is the most widely used drawer rail on the market. Commonly used types are divided into hanging type and bottom support type.

[0004] The hanging type installs the slide of the drawer guide rail at the required position of the cabinet side panel, and installs the slide rail at the required position on the outside of the left and right side panels of the drawer. The slide on the cabinet side panel is connected to the slide rails on both sides of the drawer side panel to achieve the sliding of the drawer. The drawer using this guide rail is not convenient to install, especially when installing on the cabinet, you need to put your hand into the cavity on the cabinet for placing the drawer. At this time, the installer must also ensure that his line of sight can see the internal situation of the cavity on the cabinet for placing the drawer. Usually, the cavity on the cabinet for placing the drawer does not support the installer's head and hand to be inserted together, so the installer is very strenuous during installation; the bottom-supporting type installs the slide of the drawer guide rail at the required position of the cabinet side panel, fixes the slide rail on the bottom plate of the drawer, and then connects the slide rail. The drawer used for the bottom-supporting guide rail can be fully opened and can be disassembled at will. However, both methods require additional installation of slide rails, which requires additional costs. Utility Model Content
